3/6 top set, am I still raising?

[Burdzthewurd]

Button is terrible-loose, no real info on other players. Should I fear 63 or 68 here and just call turn bet, or pop it up to make lows and straight draws pay? I'd feel sick seeing a 3-bet here. Probably a stupid question, so feel free to restate that in reply.
